Answer:
3/4
Step-by-step explanation:
full angle=2 pi
angle subtended here = 3pi/2
fraction of circumference = fraction of the angle
therefore the required fraction if 3/4
pls mark brainliest
Given : A circle and an arc subtending 3π/2 angle at center
To find : What fraction of the circumference is the arc
Solution:
Arc length = ( Angle subtended by arc at center/ 2 π ) Circumference
=> Arc length / Circumference = Angle subtended by arc at center / 2 π
Angle subtended by arc at center = 3 π/2
Substituting in the formula
=> Arc length / Circumference = (3π/2) / 2 π
=> Arc length / Circumference = 3/4
=> Arc length = (3/4) Circumference
3/4 fraction of the circumference is arc length
